Graviton Deflector Arrays grant buffs to Subspace Decompiler and Graviton Generators. So should any set graviton deflector in the game. Right now we don't have any set deflectors that grant a bonus to Subspace Decompiler, which sucks. I hope that either this change is made, or we get a set deflector in the future that does have a bonus to [SubD].
Heh, I was just looking at my deflector, and guess what- My mk12 positron deflector has [SubD], as well as [em] and [shds].
I KNEW I didn't spend that 18K in dilith for the AEGIS for a reason.
